Subsequently, an order changing operation which, isperformed by the slitter scorer apparatus as shown in FIG. 1, isdescribed hereinafter. In this apparatus, the corrugated board 7, whichhas fed successively from the double facer 8, passes between the upperand lower rolls 14 and 15 of the rotary shear 1. Thereafter, thecorrugated board passes through any one of the upper slitter scorer 2,the lower slitter scorer 2 or on the plate 46 and reaches the cut offmachine 9 of the next process through the rear guide 601. The corrugatedboard 7 which has past the rotary shear 1 is changed in course properlyby the front guide 501 and passes the slitter scorer 2 or between theupper and lower slitter scorers 2 and 2 which have been maintained inadvance in any predeterminened oreder while they are not in userespectively.

In order to change the order for the corrugated board 7 which is passingthe plate 46 or the lower slitter scorer 2, there is describedhereinafter a case where the corrugated board 7 is caused to pass theupper slitter scorer 2 which is maintained in a predetermined order.

Referring to the rotary shear 1, the handle 197 is rotated thereby tocause the cutting edges 141 of the upper roll 14 and the cutting edgesreceiving portion 151 of the lower roll 15 to be located near thecorrugated board 7 as shown in FIG. 20 so that the cutting edges 141 andthe cutting edges receiving portion 151 may be confronted with eachother with the corrugated board 7 inserted therebetween when the upperand lower rolls 14 and 15 have made almost one revolution (under onerevolution) respectively in the direction of arrows X and Y. Thereafter,the solenoid SOL91 of the solenoid-operated valve 91 (see FIG. 13) isexcited by pushing the switch P8161 (see FIG. 16) to cause the pistonrods 1851 and 1851 of the air cylinders and 185 to be projected therebyto lower the upper roll 14. A switch SW11 for indicating the orderchange (see FIG. 16) is closed together with the operation in the rotaryshear 1. Then, the motor 30 for the upper slitter scorer 2 is actuatedby pushing the switch PB111 (see FIG. After such an order changepreparing operation has been completed, order change starting switchPB162 (see FIG. 16) is pushed. Thus, the current is flowed to the relayR11. The motor 192 for the rotary shear 1 is actuated, and the upper andlower rolls l4 and 15 are rotated in the direction of the arrows X and Yas shown in FIG. 2 thereby to cut the corrugated board 7. After thestart switch PB162 has been pressed, and the set delay time of anelement T11 has been elapsed and when the iron piece 1 of the upper roll14 has been approached towards the proximity switch APSl thereby tooperate the switch, the electric passage to the solenoid SOL91 and therelay R11 is closed and the upper roll 14 is ascended, whereby the motor192 is suspended. Also, the pushing action of the switch PB162 excitesthe solenoid SOL93 of the solenoidoperated valve 93 (see FIG. 13) tocause the piston rod 5421 of the air cylinder 542 to be projected in thefeeding guide 54 of the front guide 501 thereby to ascend the guidingplate 541 to a place U2. Accordingly, the corrugated board 7 which haspast on the plate 46 or the lower slitter scorer 2 is advanced as it iscontinuously. however, the tip end of the corrugated board 7 whichappears successively from a place cut by the rotary shear 1 istransferred from the guiding plate 541 to the guiding plate 523 of theupper guide 52 and is guided to the upper slitter scorer 2 which hasdescended to the stoppers 44. As the solenoid SOL93 is demagnetizedafter the elapse of the sufficient time required for the corrugatedboard 7 to be transferrd to the upper guide 52, namely, after the elapseof the set delay time of the element T14, the guiding plate 541 isdescended to the original place D2. As the order change operation iscompleted, the switch SW11 is left open.

Subsequently, there is explained a case where the corrugated board 7which is passing the upper or lower slitter scorers 2 is caused to passon the plate 46. The same order change preparing operation as in theabovementioned operation is performed. However, the switch SW12 (seeFIG. 16), instead of the switch SW11, is closed and the switch F8111 isnot necessary to be pressed. The order change start switch PB162 (seeFIG. 16) is pressed. Thus, the rotary shear 1 cuts the corrugated board7. Also, when the switch PB162 is pressed, the solenoids SOL92 and SOL93of the solenoid-operated valves 92 and 93 (see FIG. 13) are excited.Accordingly, the piston rod 5241 of the air cylinder 524 is retractedwhile the piston rod 5421 of the air cylinder 542 is projected. Theguiding plate 523 of the upper guide 52 for the front guide 501 isascended to the place U1, while the guiding plate 541 of the feedingguide 54 is ascended to the place U2. Accordingly, the tip end of thecorrugated board 7 which appears sucessively from a cut place of thecorrugated board is transferred from the guiding plate 541 to theintermediate guide 51 and is guided onto the plate 46. After thecorrugated board 7 has been transferred to the intermediate guide 51,namely, after the elapse of the set delay time of the elements T15 andT16, the solenoids SOL92 and SOL93 are demagnetized, whereby the guidingplates 523'and 541 are descended to the original placesDl and D2. Thus,as the order change operation is completed, the witch SW12 is left open.

Then, there is explained a case wherein the corrugated board 7 which ispassing the upper slitter scorer 2 or on the plate 46 is caused to passthe lower slitter scorer 2. The order change preparing operation is alsoperformed in this case. However, the switch SW13, instad of the switchSW11, is closed. The motor 30 of the lower slitter scorer 2 is actuatedby pushing the switch PB121 (see FIG. 15), instead of the switch PBlll.Then, the order change switch PB162 (see FIG. 16) is pushed. Thecorrugated board 7 is cut by the rotary shear 1. In this case, thesolenoids SOL92 and SOL93 are not excited. Accordingly, the guidingplate 523 is located in a place D1, while the guiding plate 541 islocated in a place D2, while the guiding plate 541 is located in a placeD2. The tip end of the corrugated board 7 which comes successively fromthe cut place of the corrugated board is transferred from the guidingplate 541 onto the lower guide 53 and is guided to the lower slitterscorer which has ascended to the stoppers 44. Thus, as the order changeoperation is completed, the switch SW13 is left closed.

The corrugated board 7 which has been slit and fluted by passing theupper or lower slitter scorer 2 is guided to the entrances 91 and(or) 91of the cut off machine 9 by the rear guide 601. As the corrugated board7 which has past on the plate 46 is neither slit nor fluted, it isguided to any one of the entrance 91 or 902 of the cut off machine 9.The motor 30 of upper (lower) slitter scorer 2 which is not in use issuspended by pushing the switch P8112 (P8122). The upper slitter scorer2 which is not in use is ascended, and the edges are changed inposition, removed, added etc. for the following order change operationby an operator who rode on the frames 55 and 65 of the front guide 501and the rear guide 601. Thereafter, the upper slitter score 2 isdescended in advance to the stoppers 44, After having engaged the pawls35 and 35 with the pin rods 361 and 361 located at the lower end of thescrew rods 36 and 36 which have descended, in advance, to the upperslitter scorer 2, the switch PB131 (see FIG. 15) is pressed to normallyrotate the motor 43 and to ascend the screw rods 36 and 36, whereby theascent of the upper slitter scorer 2 is performed. When the upperslitter scorer 2 has reached its maximum ascending limit, the iron pieceF14 of the slitter scorer 2 approaches the proximity switch APS14 of thestrut 32 to operate it. Accordingly, the motor 43 is suspended and theslitter scorer 2 stops. Also, the descent of the upper slitter scorerscirer 2 is performed by pressing the switch P8142 (see FIG. 15) andreversely rotating the motor 43. When the upper slitter scorer 2 hasreached its maximum descending limit, namely, the stoppers 44, the ironpiece F15 of the slitter scorer 2 actuates the proximity switch APS15 ofthe strut 32 thereby to suspend the motor 43. The lower scorer 2 whichis not in use is descended and maintained by the operator, andthereafter, is again ascended to the stopper 44. The switch P8182 (seeFIG. 16) is pressed to excite the solenoid SOL953 of thesolenoid-operated valve 95 (see FIG. 14) and to retract the piston rods451 and 451 of the oil cylinders 45 and 45, whereby the lower slitterscorer 2 is descended. When the lower slitter scorer 2 has reached itsmaximum descending limit,

the iron piece F16 of the slitter scorer 2 approaches the proximityswitch APS16 of the strut 32. Thus, the'sole-
